Authorities in Washington County, Ore., say Sour Patch Kids one trick or treater was given on Oct. 31, 2018, tested positive for methamphetamine.

The parents were taken to the hospital as a precaution, but no kids ate the tainted candy.

Authorities actually warned parents in the town not to throw out the candy, but instead preserve it as evidence.

"Leave it be. Don't throw it away. We want you to leave it just as you have found it if you think it's been tampered with," Washington County Sheriff's Office Det. Mark Polovny told Portland ABC affiliate KATU.

Officials said no one else in the town reported getting sick from any candy. The sheriff's office said they released the information "out of an abundance of caution."
